CFD packages

[BioGeezer]

Is it possible to download any simple CFD packages from the net and if so, what kind of limitations are there?

I suggest you take a look at

http://www.cfd-online.com

for freeware/shareware and trial versions of commerical cfd codes.

I've tried a few of the more inexpensive CFD programs for airfoil/wing work, and my opinion is they aren't there yet. Klugy, non-user friendly, and questionable results has been my experience so far.

If you're serious, talk to Fluent.

You have to be careful with CFD software because I don`t know if they now can take into account boundary layer separation!

There are some shareware. In my experience, I suggest AirfoilAnalysis shareware in versiontracker.com. Is the finest implementation of the Vortice Panel Method for windows and Mac I ever seen. Check it out. Obviously, it has all the assumptions and limitations of the Potencial Flow theory. That are low mach,incompressible,inviscid and steady flow.

You can solve unsteady problems using potential flow theory....
